HTML Coding - Frame sets 2 What are Frames? Frames allow independent navigation and content to two (or more) locations on a single browser screen Frames allow multiple "windows" in a single browser page

HTML Coding - Frame sets 3 Advantages / Disadvantages of Frames Advantages  Allow multiple content on a single page  Allow linked content (such as a table of contents)  Allow separate scrollable regions on a page Disadvantages  Breaks down the traditional 1 file equals 1 web-page linkage  Adds considerable complexity to the coding process  Implementation is fairly browser specific  Errors can be extremely difficult to identify

HTML Coding - Frame sets 5 Basics of Frame Design - content of frame1.htm file Frame example Notice - there is NOT a … tag set in the frame definition. This is NOT a mistake in the example code.

HTML Coding - Frame sets 6 Basics of Frame Design - Defining the frameset Frame example The Frameset tags define that this frame will have two rows. The top row will be 100 pixels tall, the second row will receive whatever space remains.

HTML Coding - Frame sets 7 Basics of Frame Design Defining the top row Frame example The FRAME tags define the two rows of the frame. The name entry is technically optional, but highly recommended. The SRC tag defines the content of the frame when the frameset is initially loaded.

HTML Coding - Frame sets 8 Content of frame1top.htm file This is the top row content This is the top row of the frame Link #1 Link #2 Link #3 Return to Original Notice how clicking on each link changes the content in the bottom frame, without changing anything in the top.

HTML Coding - Frame sets 9 Basics of Frame Design Defining the bottom row Frame example This Frame tag defines the bottom of the browser window, which will be the "large size" window on the screen. The name entry (bottom_row) shows up in links in the frame1top.htm file. The initial content of the is defined in the SRC tag entry.

HTML Coding - Frame sets 12 How the links in frame1top.htm function {content removed for space purposes} This is the top row of the frame Link #1 Link #2 Link #3 Return to Original {content removed for space purposes} The link has the HREF="…" entry we have used earlier this semester.

HTML Coding - Frame sets 15 Defining a frameset with columns instead of rows. Frame example - Columns <FRAME NAME="left_side" SRC="frame2menu.htm" SCROLLING="yes"> <FRAME NAME="right_side" SRC="frameintro.htm" SCROLLING="yes">

HTML Coding - Frame sets 16 The substantive changes are highlighted. Frame example - Columns <FRAME NAME="left_side" SRC="frame2menu.htm" SCROLLING="yes"> <FRAME NAME="right_side" SRC="frameintro.htm" SCROLLING="yes">

HTML Coding - Frame sets 17 Left-side menu content of frame2menu.htm file This is the left side content This is the table of contents listings for the left side frame {MORE CONTENT ON THE NEXT PAGE}

Left-side content (continued) Link #1 Packer graphics page. Link #2 Packer schedule page. Link #3 Myerscough Websume Page. Return to Original Being a team member Notice how clicking on each link changes the content in the right side frame, without changing anything in the left side.

Defining table of contents as a list Link #1 Packer graphics page. Link #2 Packer schedule page. Link #3 Myerscough Websume Page. Return to Original Being a team member Notice how clicking on each link changes the content in the right side frame, without changing anything in the left side.

Defining each of the hyperlinks (Note the target names in each) Link #1 Packer graphics page. Link #2 Packer schedule page. Link #3 Myerscough Websume Page. Return to Original Being a team member Notice how clicking on each link changes the content in the right side frame, without changing anything in the left side.

HTML Coding - Frame sets 22 Options in defining the framesets Defines a two row frameset, the top row will be 100 pixels tall, the second row receives the remaining space on the screen. Defines a two row frameset, where the bottom row will always be 4 times larger than the top row, regardless of browser window. demonstrates this setting.

HTML Coding - Frame sets 23 More options in defining the framesets Defines a three row frameset. The top row will be 100 pixels tall, the bottom row will be 75 pixels tall. The middle row will receive whatever space remains. NOT A RECOMMENDED APPROACH. This setting does not provide for a "rest of the browser window" setting. The net effect is that the top row will always be twice as large as the bottom row - since 200 is twice as large as 100. ALWAYS allow for a wildcard (*) setting for the rest of the browser window.

HTML Coding - Frame sets 24 Defining column settings Follows the same principles as row definitions Columns are defined in left to right order Same issue on wildcard settings - always allows for one

HTML Coding - Frame sets 25 3 methods for combining Rows and columns in a frameset Defining rows and columns simultaneously in the FRAMESET definition  See page 171 in Castro text Embedding a second frameset within the original frameset definition  See pages in Castro text  Make sure the … definition completely replaces the <FRAME… definition  illustrates this methodology. Defining a FRAMESET in one of the HTML files that serves as the source code for a frame  Easy to lose track of where you are at in the frame structure
